To all 2070mm it may concern.-

Be it known that we, FRANK H. BROWN and JOHN E. HANRAHAN, of Baltimore city, and Gnonsn A. Bornnzv, of Mount Washington, in the county of Baltimore and State of l Maryland, have invented certain new and useful Improvements in Matrix-Making, Means to PositionPlates and Blocks and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention pertains to matrix-making, 1 among the objects of which is to provide l means by which a type character and a mal trix-pla-te are positioned relatively to each other in order that the type character will be located quickly, accurately, and absolutely to a predetermined position with reference I to the matrix-plate.

I'Vith the introduction of the sorts-machine for casting type, invented by these same inventors, the art of producing type at this time is being revolutionized, for the reason that instead of making type under the present foundry practice with skilled labor and then distributing the type throughout the country for printers to use the printers are now producing type in their oiiices with unskilled labor. This results in a great sav- .ing of time and money and affords convenience in procuring immediately type and sorts when desired. This invention necessi tated the creation of various systems and inventions, not only with relation to the typecasting machine proper, but also in molds, l mold-making, matrices, and matrix-making, and to one of these systems the present invention relates.

In the accompanying drawings, Figure 1 is a front view of a guiding frame or holder. Fig. 2 is a side view of the same. Fig. 3 is a front view of Fig. 1 with a master-block and matrix-plate inserted therein ready for attaching. Fig. A is a side view of Fig. 3. Figs. 5 and 6 are front and side views of a masterblock. Figs. 7 and 8 are front and side views of a matrixplate; Figs. 9 and 10, I front and side view of modified master-block]v provided with a type character and guidingj block; Figs. 11 and 12, similar views of 9 l and with a matrix-plate located therein ready for deposition; Figs. 13 and 14, still further modified views of a master-block ,having a character and positioning-pins;

Figs. 15 and 16, views of matrix-plate provided with. holes to coact with the pins shown in Figs. 13 and 14:.

He'retofore in matrix-making wherein de position has been used to form the character in the matrix-plate complicated and unsatisfactory means have been employed to approximately locate the character in reference to its correct position on the plate and afterward the plate altered and finished to suit the position of the type character in deposition therein. With the present invention all matrix-plates B used are made to a standard and uniform size, irrespective of the size and style of type character, and provided with a hole to be filled with deposition of suitable size to accommodate the particular size of the character. Master-blocks A are also herein used which contain the type character, each master-block containing one individual character or logotype. With these two, master-block A and matrix-plate B, are combined or arranged positive positioning means by which the characteron the block A is correctly, absolutely, and quickly located in the correct position it is to occupy on the matrix-plate B when the block and plate are combined ready for the deposition process by which the type character is reproduced and formed in the plate B in its proper position.

As shown in Fig. 1, in this instance the positioning means consists of a holder or guiding-frame 0, provided with projections c on each of its corners and so arranged in form, size, and location that a master-block A neatly fits between said projections, and likewise a matrix-plate B, the height of the projections 0 being sufficient to accommodate both.

In preparing the block and plate for deposition the block A is first placed between the projections c, with the type character exposed, and the matrix-plate B then placed on top of the block, and as both the block and plate are of the same size the hole I) and type character are correctly located and the type character is in its proper position in reference to the plate. The block A and plate B while thus positioned and held by the said means are united together by tipping them with solder at e e, after which they are removed from the frame and are ready for the deposition process, being absolutely in their relative position to each other and thewhole accomplished without any measuring, adjusting, or uncertain positioning and requiring little time by unskilled persons.

n Figs. 9, 10, 11, and 12 a modification is shown in which means difiering from the foregoing, in that the block A is made larger than in the former case, and instead of having a separate frame C, the block A is provided with means C, consisting of projections having their inside surface properly arranged and of the size to take the matrixplate B. This means also answers the same purpose as the frame C, and in using the same the plate B is attached to the block A in any suitable manner, when the whole is ready for the deposition process.

Figs. 13, 14, 15, and 16 show another modification of securing the blockA and plate B together by other means, consisting of pins C and matrix-plate provided with holes 0, both of which are correctly located, so that when the two are put together the character will be in its roper position in relation to the matriX-p ate, the plate being secured to the block by slightly riveting the pins C when the same is ready for deposition process.

By this invention means are provided by which the matrix-plate and type character are always placed in their proper relative position for deposition without requiring skilled labor and reducing the cost of matrices to such an extent that printers are enabled to plrocure the same at a price which is non-pro- 'bitive to producing type in their oflices instead of purchasing it from foundries as heretofore. It is obvious that other means can be devised by which the same result would be accomplished. Therefore we include all equivalent means as within our invention.

Having described our invention, what we claim, and desire to secure under United States Letters Patent, is

1. A master-block provided with an integral type character, a matrix plate, and means to properly position the two, one upon the other, whereby the type character will be in its proper position relative to the plate.

2. A master block provided with. a type character, a matrix-plate, and means for holding said block and plate with their edges in juxtaposition.

3. A master-block rovided with a type character, a matriX-p ateprovided with an opening, and means engaging the edges of said plate for bringing the opening thereof in juxtaposition with said type character.

4. A master-block provided with an integral type character, a matrix-plate provided with an opening, and means for engaging the edges of said matrix-plate to bring the open ing thereof opposite said type character.

5. A master-block provided with a type character, and ing provided with means for engaging said plate, whereby the type character will be properly positioned relative to said plate.

6. A master-block provided with a type character, and a matrix-plate, said block being provided with means for engaging the edges of said plate, whereby the type character will be properly positioned relative to said p ate.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
